I added videos to the unit 2 tab under unit 2C review material at the bottom of the page. There are video's on how to graph in vertex and standard form, as well as how to find max, min, and vertex on the calcultor. Not to mention the Quadratic formula song so you can memorize the Q.F. for the quiz. You can thank Julian and Brandon for requesting this material being added. If it wasn't for them then I wouldn't have added it :)
